Abstract

The invention relates to a linear electric motor primary heat dissipation structure applied to an underground oil extractor. The structure comprises a primary yoke part, wherein a left flange and a right flange are arranged at the two ends of the primary yoke part, an inner pipe is arranged axially between the left flange and the right flange; the primary yoke part, the left flange, the right flange and the inner pipe form an electric motor primary inner chamber; through holes are respectively arranged on the left flange, the right flange and the primary yoke part; and insulating heat dissipation objects injected into the electric motor primary inner chamber through the through holes are arranged in the electric motor primary inner chamber. In the invention, as the insulating heat dissipation objects injected into the electric motor primary inner chamber through the through holes of the flanges are arranged in the electric motor primary inner chamber, not only can heat generated by electric motor coils be effectively absorbed and transmitted outwards, but also the insulating function can be carried out; and in addition, combination seal elements arranged at the two ends of the electric motor primary inner chamber can prevent underground harmful substances from entering the underground oil extractor and ensure the operating stability and durability of the electric motor.

Description

technical field [0001] The invention relates to equipment for oil extraction, in particular to a primary heat dissipation structure of a linear motor for an underground oil extraction machine. Background technique [0002] At present, the oil production equipment mainly includes the beam extraction machine and the oil pump device. The whole set of equipment is composed of the surface, the downhole and the control part. The above-mentioned oil production equipment has the disadvantages of high energy consumption, high failure rate, and poor reliability. The power factor of the motor used in the oil extraction machine is low, generally between 25-55%. In addition, the elastic deformation of the rod during the driving of the several-ton sucker rod and the oil pumping process seriously affects the system efficiency. In addition, the above-mentioned structural design, The phenomenon that the sucker rod is worn out or the wall of the pumping tube is worn out often occurs, which se...
